TIRE FOR WHEELS.

Application filed December 3, 1910.

To all whom it may concern: 7

Be it known thatI, WILLIAM H. BLAKE, a citizen of the United States, residing at J ersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Tires for Wheels, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to improvements in tires for road vehicles and particularly to improvements in tires of resilient material, such as rubber blocks, for heavy vehicles of the self-propelled type (6. 9., motor trucks and motor wagons); and an object of this invention is to provide a tire of the character just referred to with means for preventing wear of the resilient material by protecting the same from the abrading act-ion of the roadway.

Another object of this invention is to provide a resilient tire in which the amount of the resilient material may be reduced to a minimum without sacrificing the resiliency of the tire, and thereby to reduce the cost of such tires. 5

A third object of this invention is to provide a resilient vehicle tire the cost of the upkeep of which will be small, which may be readily repaired by an unskilled person and which will be durable and eflicient in use.

In the drawings illustrating the principle of this invention and the best mode in which I have contemplated applying that principle, Figure 1 is a plan of so much of a tire as is necessary to illustrate this invention; Fig. 2 is a side elevation of the same; Fig. 3 is a section on the line A.A of Fig. 1; Fig. 4 is a perspective view of the cap or shoe detached and I inverted; Fig. 5 is a detail showing in perspective the retaining plate detached; and Fig. 6 is a detail showing a slightly modified form of the cap illustrated in Fig. 4.

Referring to Figs. 1 to 5, inclusive, the rim (6 of the wheel is formed in its outer face or tread b with two seriesof dovetailshaped pockets or recesses c, the pockets of one series being out of register or staggered with relation to, the pockets of the other series and both series of pockets being circumferentially arranged. The pockets eX- tend axially of the wheel or transversely of the tread of the rim and are open at their outer ends. Into each pocket is slipped from its outer open end a rubber block d. the base Specification of Letters Patent.

of which flares outwardly and downwardly from the middle of the block and is, therefore, wedge-shaped and thereby adapted to fit snugly in the dovetail-shaped pocket 0. The top portions (those which project beyond the tread face and lie outside of the pockets) of the blocks cl flare upwardly and outwardly and are wedge-shaped; and over these top portions are slipped the metal caps or shoes 0 each of which is formed with lateral walls or sides f, a top 9 having a projecting end 9', and a downwardly-extending end flange h at the end opposite the part 9. Near the latter each lateral wall is formed at its end with an outwardlyextending ear or lug 2' having a notch 71 in one of its edges. A retaining plate j overlies each pair of adjacent ears 2' and is formed with a hole j through which is passed a bolt 70 the head of which lies in a countersunk recess j at one end of the hole j and is prevented from turning by the plane walls of the recess. The threaded end of the bolt 70 extends through the notches i of the adjacent ears 21 and on it is screwed a nut 7c by tightening which the head of the bolt 70 is drawn into the recess y' and the ears 7) and the retaining plate are firmly fastened together. The ends of the retaining plate j bear against the innerends of adjacent blocks d and the projecting ends 9 of the shoes or caps e overhang the ends of the plate j so as to prevent displacement thereof in a radial direction away from the tread of the rim. The lateral walls of the cap or shoe may converge toward the outer end or the end formed with the end flange h, as is shown in Fig. 6. This makes the cap fit tightly on the rubber block, which is compressed between the converging lateral walls f.

Since the metallic caps prevent the wear of the rubber block, the latter need not be made as large as they are now made in un protected tires; and from this it results that a saving in rubber is effected by the use of my invention. Economy of rubber also results from the fact that the metallic caps for the blocks greatly lengthen the life of the latter. In case anyblock gives out, the driver, who carries a supply of extra caps and blocks, may readily replace the worn-out block, since the parts are readily detachable from each other, as hereinbefore explained. Even an unskilled person may detach these parts and may replace the worn-out parts with new ones, whereby the 'cost'of'upkeep is greatly lessened.

In accordance with the provisions of the patent statutes, I have described the principle of operation of my invention, together with the apparatus which I now consider to represent the best embodnnent thereof; but

I desire to have it understood that the appae ratus shown is only representative and that.

theinvention can be carried out by other means. I
